Ten fittest cities according to American Fitness Institute: Is Denver getting flabbier?

Back in February, we shared a list of America's ten fittest cities as compiled by Sharecare.com -- a roster on which Denver finished first. Now, however, the American Fitness Institute has issued rankings of its own, and while Denver finishes high, it's definitely not number one. Is Denver slipping down the fitness scale? Or is this an example of how results can differ from one study to the next? After all, three cities cited by AFI weren't even mentioned by Sharecare.com, including the top two.

Count down the former's photo-illustrated top ten below, featuring AFI data and list comparisons -- and click here to see the complete (and massive) American Fitness Institute report.
